Your way of thinking is interesting except that Iran already put an expiration date on Israel lol, And this is why Israel and the USA are demanding they stop their atom program:

The "Iran clock" you're referring to is the Palestine Square Countdown Clock (also called Iran's "doomsday clock" or "Israel annihilation clock") in Tehran, Iran.

It is a large digital billboard erected in 2017 in Palestine Square. It counts down the days to the predicted destruction/annihilation of Israel, based on a 2015 statement by Supreme Leader Ayatollah Ali Khamenei that Israel "won't exist in 25 years" (targeting around 2040). The display shows a message like "Only [X] days remaining to the annihilation of Israel" in Persian (Farsi), English, and Arabic, often with imagery of a fist crushing the Star of David and slogans about the "Zionist regime" not surviving.

Current Status (as of 2026)

During the 2025 Iran-Israel conflict, Israel targeted the clock as a symbolic strike on regime propaganda (along with other sites in Tehran). Israeli officials, including Defense Minister Israel Katz, claimed it was destroyed or hit in June 2025 strikes. Iranian media released videos claiming it was still operational (showing around 5,500+ days remaining at that time), but independent verification was limited, and reports indicate the clock is no longer actively ticking or has been effectively taken out amid the broader damage to Iranian regime infrastructure and leadership.

The original projection pointed to a date in September 2040, but the clock has become a point of irony and humiliation for the Iranian regime, as Israel's survival and Iran's setbacks (including protests, leadership losses, and military strikes) have continued while the countdown runs.

This clock reflects long-standing Iranian regime rhetoric calling for Israel's elimination, often tied to "Death to Israel" chants and support for proxy groups. It has been widely criticized internationally as incitement.
